So I was playing on my survival world and I wanted bees so I grew a tree with a flower next to it and got a full beehive. After collecting from it for a bit, I noticed that the bees disappeared, so I went to look for them nearby. All of a sudden, about 100 blocks out from the original hive, I found about 20 bees congregating near a single beehive on a tree in a random forest. I'm assuming that these 20 bees are all from random beehives I've loaded in (or maybe not), and the bees are for some reason going towards it. So basically, bees from random places are all going towards a single random hive that is loaded in. This hive is in chunks that are loaded when I'm at my base if that has anything to do with it. 

All the glowing things are bees, and there were even more a bit farther away from the hive (like 50 blocks). The hive shown is the one hive they were all near. Yes I checked around for more hives, and there were none.
